Issue
Can a DMS-350A controller replace a DMS-35 controller?
Environment
DMS
Cause
DMS-35 has failed and customer has a spare DMS-350A from a previous retrofit.
Resolution
Yes, it is possible.
To replace a DMS-35 with a DMS-350A, ensure that at least one DCM is included (the MicroSmart controllers connect to the DCM and the DCM connects to the DMS-350A).
Ensure the firmware level in the DMS-350A & DCM is the same (or higher) than the MicroSmart controllers. For example, if the MicroSmart controllers are revision 10.x, then the DMS-350A & DCM must be revision 10.x or 11.x.
The DMS-35 database will not install directly into a DMS-350A because of the DCM. The points in the MicroSmart controllers will have to be re-linked thereby creating a new database.
